I have a string of HTML in Rails. I’d like to truncate the string

  • 0

I have a string of HTML in Rails. I’d like to truncate the string after a certain number of characters not including the HTML markup. Also, if the split happens to fall in the middle of an opening and closing tag, I’d like to close the open tag/s. For example;

html = "123<a href='#'>456</a>7890"
truncate_markup(html, :length => 5) --> "123<a href='#'>45</a>"

    There are two completely different solutions both with the same name: truncate_html

    1. https://github.com/ianwhite/truncate_html : This is a gem and uses an html parser (nokogiri)
    2. https://github.com/hgmnz/truncate_html : This is a file you put in your helpers directory. It uses regular expressions and has no dependencies.
